A passive pickup that utilizes electromagnetic coils comprising circuits that are connected in series and placed underneath and parallel to the strings of the electrical instrument. Each circuit within the passive pickup can be run through separate amplifiers in stereo or combined with standard guitar pickup signals and run through one or more amplifiers. The passive string isolating pickup is directed at allowing utilization of signal processing (guitar effects) in a string-isolated mono or stereo manner and the adjustment the volume and tone of isolated strings when wired in conjunction with volume and tone potentiometers.
